Answer:
sqrt 24
Step-by-step explanation:
x^2-9=-15
x^2-9+9=-15+9
x^2=24
x=sqrt 24
Equation: x² - 9 = -15
Step-by-step solution:
• Move -9 to right side
-> x² = -15 + 9
• Solve
-> x² = -6
• Root of both sides
-> x = √-6
This is wrong because √-1 = imaginary number and it doesn't look like you're dealing with imaginary numbers so check the equation again
